We consider the physical properties of matter outflow from active galactic nuclei in a unification model. The unification model of the outflow assumes that the source of the absorbing matter is the internal surface of the obscuring torus, and the model includes two-phase gas dynamics, radiation transfer and absorption spectrum calculations in the ultraviolet and X-ray bands. We analyse the radial dependences of ionization, radiation pressure and absorption features on the model input parameters. We briefly discuss several questions about the mass source of the flow, its covering factors, the nature of narrow absorption details and others.
